  • Title: [Intraosseous pressure measurement and bone marrow venography in idiopathic necrosis of femoral head].
    Author: Li YZ, Yue T.
    Journal: Zhongguo Yi Xue Ke Xue Yuan Xue Bao; 1989 Oct; 11(5):338-43. PubMed ID: 2534613.
    Abstract:
    Intraosseous pressure measurement and bone marrow venography were performed in 14 patients (25 hips) with idiopathic necrosis of femoral head. Increase of intraosseous baseline pressure was found in 95% of hips, positive stress test found in 91% of hips and venous stasis present in all cases. Core decompression could reduce intraosseous pressure and improve venous drainage. It was suggested that intraosseous hyperpressure and venous stasis play an important role in the pathogenesis of idiopathic necrosis of femoral head. The authors suggest that intraosseous pressure measurement and bone marrow venography are sensitive in revealing early stage changes of idiopathic femoral head necrosis.
